How does BuildingCensus know THE JMA GROUP LLC is at these addresses?

Each location is a business record whose premises address was matched to a county office parcel (record types on this page: Seattle business licence). The match method and confidence are shown on every row.

A record at an address is evidence that the business operates there, not a lease: records lag moves by months, and businesses without a local record at an address do not appear.

Data provenance — public records only

Seattle / King County — King County Assessor bulk extracts and Seattle open data. Washington law restricts commercial use of lists of individuals, so this metro is built without personal names by design: the county's name-stripped account file provides mailing addresses (portfolios group by mailing cluster, unnamed), sales show price and date but never buyer or seller, and tenants are business licence trade names.

Every fact on this page is drawn from the government records above — no listing sites, no scraped platforms, no third-party images. Facts from public records are uncopyrightable; each tenancy row carries its source and match confidence. Records can lag reality — a business-tax receipt or registration at an address is evidence of occupancy, not a lease confirmation.

Dataset updated September 2026 . Locations from Seattle / King County business records matched to county office parcels.
